Journaled in suitable bearings and journaled inthese bearing brackets 17 carried bythe frame at the rear end thereof isa shaft 18 upon which are fixed sprocket is a rea-raxle. 2i and on the.outer ends of wheels 19 alining respectively with the 105 tlrereariaxle2.are mounted ground wheels 3. sprocket wheels 15. Over thesel aliningV,Aippropriatel'y secured to the side bar of sprocket wheels are trainedendless chains the frame 1i adjacent to the forward end 20 andV spanningthe space betw en the thereof are ground casters 4; that cooperatechains 2O and appropriately fastened to with the ground' wheels 31 tosupport. the such chains are' conveyor elements, each 110 Yteeth 22spaced apart equal distances.

These conveyor elements are preferably spaced' apart equal distancesalong the lengths of the chains, as shown in Figures 1, 2 and 3 oftherdrawings. in order to maintain the chains of the conveyor tight ortaut employ means that acts upon the bearing brackets 17 to slide thebrackets 17 relatively to the side boards 7 upon the pin and slot-connections'lt In the present instance this'tension means,rs hownclearly in Figure 8, comprises a bracket 23V fastened to the lower edgeof each side board 7behindVV the corresponding bearing bracket 17 3 arod 24 having one end portion slidably mounted in the bracket 23 andtheother end portion secured to the bearing bracket 17. Threaded upon thelast mentioned end portion of the rod 24-v is an adjusting nutl25 andencircling the rod 24 between the adjusting.

nut 25 and the bracket 23 is an expansion spring 2G; These springs actupon the nuts 25 to-force the bearing brackets 17 outv` wardly along'thelower edges of the side boards 7, thereby maintaining the chains tight.YShould it be desired to take-up or let out the tension of the spring 26the nut-s 25 may be manipulated.

In theV rotation of thefshatt 1e the sprocket wheels'15 fixed theretoimpart movement to the chains 20,-thereby operating the conveyor so thatVthe upper reaches or runs ofv the chain will be moved over the guidebars 12, the inclined end portions of such bars facilitating the travelof the conveyor elements on the chains along the bottom of the housingformed by the side boards, crossl bars and longitudinal bars. As thecon- Y veyor belt travels through the housing the contents thereof arecarried upwardly and discharged through the top end of the housing andthus may drop into the wagon or otherreceptacle at the forward end ofthe loader, while the lower run or reach of the conveyor travelsdownwardly in order to take up a new load; Y

VExtending across the side boards 7 adjacent'to the lower ends thereofand journaled'in suitable bearings carried by such side boards is ahorizontal shaft 27 arranged above and slightly tothe rear of the shaftV1l and fixed to the shaft 27 and spaced apart equal distances arecurved tines 28 that are arranged substantially concentrically of thebottom end of theconveyor, so that'as the loader travels over the groundthe tines 28 will gather the hay so thatvthe gathered hay .maybe takenup by the conveyor element and carriedV through the housing, viouslydescribed.V Y Y Y These tines 28 on the shaft 27 are capable of swingingmovement to active and inactivepositions, and in the present instance asprethe mechanism for so swinging the tines 27 comprises an arm 29Vfixedto one end 'of the shaft27-V and depending therefrom, as Y Y shown inFigure 1. Connected to the lower end of the arm 29is one end of aretractile spring 30, the otherv'end vof which is fastened to the outersurfaceof the adjacent side boards 7, theV spring acting to hold thetines 28V normally in active position; Also connected tothe lower endofthe arm active and the tines may beheld in inactive position bythevdog and notchesfin the quadrant33. V

n order that the hayy will not become congested in the tinesi28 atgthelower end of the conveyor l employan agitatingor de-- livery mechanismwhich, in this form of invention, comprises a shaft 3e formed'with aplurality ofA cranks 35Y spaced apart equal distances. This crankshaft34 is arranged transversely of 'the housing at the lower end'theieofandfthe ends of the crank shaft 34: are journaledrin bearings 36 canried bythe upper edges of the side boards 7. 'Y

Connected to the cranks 35, respectively, are agitating elements eachcomprising a bar'37 having one end provided with a bearing 38 as shownin Figure 5 of the drawings, to. re-V ceive the corresponding crank 35and the'VV other end equipped with tines 39 `extending rearwardly anddownwardly.-V These bars 37 are arranged longitudinally of the hous ing,are spaced apart equal distances and, at Y their centralportionsa restrespectively between guide prongs 40 carried' by arod 4:1 that extendsacross theV housing behind the crank shaft,which crank shaft'is securedat its ends to the Aside boards of the housing.

The times 39 extend `intofthe spaces between the tines 28, asclearlyshown in Figures 2 Vand 3 of the drawings, and in the operation of thecrank shaft an-oscillatory motion is imparted to fthe bars 37,so' thatthe tines 39 will enter the/spaces between the .tines 28 and agitatethehayg'athered by the tines 28, with'therresult that suchliay will bedelivered to the conveyor. 1 ln order to drive theshafts 14: and 34 anysuitable drive mechanism may beemployed.

In the present instance the corresponding ends ofthe shafts '14j and 34at one sideof llO ing end portion of the axle 2 is equipped Y with asprocket wheel 44 and over `these sprocket wheels istrained an endlesschain Y L5 by which motion is imparted from the rear axle to the shafts14 and 34, as clearly shown in Figures 1 and 3 of the drawings.

In the modified construction shown in Figure 9 I have shown anothermeans for guiding the agitating elements, and in this form each bar 37rests upon a roller 46 carried by the shaft 41, and surrounding theshaft 41 are coils 47 formed with outwardly extending arms 48 arrangedupon the respective sides of the bar 37. The outer ends of the arms 48carry rollers 49 that bear upon the upper edge of the bar 37, as clearlyillustrated in Figure 9 of the drawings.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of myimproved hay loader will be readily apparent, and it will be seen that Ihave provided a hay loader wherein all of the parts are so arranged andcorelated as to be readily accessible so that they may be easilyrepaired and replaced.

Vhile I have herein shown and described one preferred form of myinvention by Way of illustration, I wish it to be understood that I donot limit or confine myself to the precise details of constructionherein shown and described, as modifications and varia tions may be madewithin the scope of the claim and without departing from the spirit ofmy invention.

Having thus described the invention, what is claimed as new, is

In a hay loader, a Wheeled frame including a rear axle and ground wheelsthereon, a conveyor housing on said frame extending upwardly therefromat an angle thereto and having its rear end connected to the frame andits forward end arranged above the frame, said housing comprising sideboards and cross bars connecting said side boards, a conveyor comprisingsprocket Wheels arranged at the top and bottom ends of said housing,respectively, endless chains t-rained over said sprocket wheels,conveyor elements arranged transversely of said chains and securedthereto and spaced apart equal distances and adapted when on the upperrun of the chains to enter the housing and on the lower run of thechains to leave the housing, ground engaging tines at the lower end ofsaid housing designed to gather the hay and deliver the same to saidconveyor, agitating elements arranged between said tines at the lowerend of said conveyor and designed to agitate the hay in the tines tofacilitate the delivery thereof to said conveyor, a crank shaftconnected to said agitator elements for oscillating the latter toagitate the hay, means for driving said conveyor and said crank shaft,said means including sprocket wheels on said axle, said crank shaft andone of the conveyor shafts and an endless chain trained over all of saidsprocket wheels.

In testimony whereof, I aiiix my signature.

HENRY J. FERSDAI-IL.
